SpringMVC传递multiple类型select后台Controller的接收方法

Spring MVC在接收集合请求参数时，需要在Controller方法的集合参数里前添加@RequestBody，而@RequestBody默认接收的enctype (MIME编码)是application/json

     $("#submit").click(function(){
         var sitename = "";
         $("#selectSite option:selected").each(function(){
             sitename+=$(this).text()+",";
         });
         if(sitename.lastIndexOf(',') >0) sitename = sitename.substring(0, sitename.length - 1);
        // alert($("#confForm").serialize());
         $.ajax({
              type:"post",
              url:"/smcnew/conf/add",
              dataType:"json",
              data:{
                  "name":$("#name").val(),
                  "site.uri":$("#selectSite").val()+"",
                  "site.name":sitename,
              },
              success:function(data){
                  
              }
          });  
     });

springMVC接收：

@RequestMapping("/add")
    public void addConf(ConferenceInfo infoEx,@RequestParam("site.uri")List<String> siteuri,
            @RequestParam("site.name")List<String> sitename){
        System.out.println(infoEx.getBeginTime()+infoEx.getName());
        }
